Description

The invention relates to a method for controlling Pests according to the preamble of claim 1.

Such a method is described in DE 195 06 200 A1 described. Measures to control pests, which are outside of a shell or a tent formed treatment room are not provided see.

The wooden equipment and exhibits of church women Rooms and museums are often of wood pests, such as Anobium punctatum infested. The infestation extends thereby on the exhibits and Depotgüter or on the built wooden objects, such as high altars, pulpits, Stools, organs, side altars, figures, crosses, medals Lons, Stations of the Cross, etc. In many cases the entire church interior sealed and fumigated how proposed in DE 195 06 631 A1. fumigants are the only insecticidal chemicals lien, in all material layers and depths, in which Insect stages live, can penetrate and all Safe kill insect stages. Require fumigants However, a costly preparation before her Application, as a sufficient gastightness of the treat must be present in order to be able to high concentrations can act for a sufficiently long time. Fumigation is broadly effective, but relative  expensive. Therefore, the room to be fumigated is tried volume as small as possible.

In many cases, treatment rooms such as Kir not all wooden objects are affected by anobia, but often only a few parts. Sometimes limited Infestation z. B. only on the high altar.

The prior art is in such cases, for. B. the High altar to be separated from church interior, z. B. by sufficiently gas-tight housing in foils or installation in a foil cage. The enclosed altar is then in a so-called partial fumigation with a fumigant fumigated, leaving the rest unaffected church interior for cost reduction reasons remains untreated. decision dend is that the rest, untreated interior actually not affected by anoblast larvae or pupae otherwise a reinfection of the gassed altar stattfin could, because fumigants have not prevented the protection, there  i. R. outgass without residue. incoming Infestation checks on the rest of the interior must take place Find. In the past, however, it appeared that "part fumigates "Kunstgerüter in church interiors frequently wiederbe fall. It must surely be excluded that after the partial fumigation or after the partial fumigation the be wooden artifacts are re-infested quickly.

In the reference Gerhard Binker: "Pest Control: Help for Maria Hilf" in building 7-8 / 92 , pp 50 to 52, a method for pest control is described in which no partial fumigation takes place, but the entire church interior is fumigated. There is mentioned that after fumigation of the church interior in addition, the entire roof truss construction woodwork, which is located outside the church interior, was impregnated with a liquid wood preservative to fight in the loft there existing Holzschädlingsbe fall. This additional method is unsuitable for a church interior with partial fumigation.

The object of the invention is a method according to the Ober Concept of claim 1 to propose, in the case of Teilbe gassing a reinfection of the fumigated objects or Goods is avoided by pests.

The above task is due to the features of claim 1. Before or after the Foil enclosure of the art objects, a Teilbe be subjected to gassing, or during the gas exposure time the partial fumigation or at least shortly before dismantling or Removal of the enclosure after the partial fumigation is the  remaining, not fumigated church interior or museum room against adults and / or against eggs of wood pests or pests specifically treated with an insecticide, however, this is not a fumigant by itself.

It could namely be found that in a Teilbe gassing in the time of flight of the pests or in time the adults of the pests occur, these in the rest Hide or hide a non-fumigated treatment room are present and after the partial fumigation then on the fumigated goods arrive or fly and these again infect. It could also be found that with wood pests this Reinfektion very rarely from outside the treatment room, so from the outside exercise or by the outdoors, but only by sexually mature adults living in the non-fumigated zone understandably survived, since here the gassing medium did not influence. Partial fumigation is usually much cheaper than Gesamtbegasungen, so Fumigation in which the entire room is more elaborate Sealing all building openings and leaks, how windows, doors, cracks etc. are fumigated. By but the invention will be outside the fumigated zone adults or their eggs or on Surfaces present larvae and pupae as well as caterpillars targeted cost-effectively killed without an expensive Total fumigation must be performed. It may be all However, there are no stages of development, such as larvae and pupae in Materials outside the fumigated zone will be present since the insecticides used are not fumigants and not deep z. B. are able to penetrate the wood (eg. sit there the larvae and pupae of the Anobien) in the counter set to fumigants, all the depths and areas to capture. That's why before running the insecticide Treatment in non-  fumigated treatment room to ensure that no already advanced infestation, esp Anobienbefall, living in materials larvae and / or dolls in the nichtzubega send zone is present.

The invention "partial fumigation plus insecticide treatment" is like after a "Total fumigation" of the entire room ensures that all pests in the entire room dead but this is now much cheaper compared to a total fumigation is reached.

In particular by Raumvernebelung or fumigation be by the insecticide Be action z. For example, the beetles of the Anobiens as adults in the remaining untreated church interior or museum / museum depot killed. The same applies to clothes moths, carpet beetles, fur and museum beetles, etc. It can also or additionally spray, in particular on walls, ceilings or other surfaces. Also possible are Juvenoids as insecticides, such as pyriproxyfen, which prevents insect metamorphosis and thus sterility of the insect tiger pests, ie a reproduction of the beetle is no longer possible.

As insecticidal agents have particularly favorable Chlorpyrifos and / or Dichlorvos and / or fenitrothion and / or pyrethroids, in particular pyrethrins and / or Naturpy Rethrum proven, as they also have a high Austreibeeffekt and / or large feeding reject possess the repellent effect. These can be in their effect by synergists, such as Piperonyl butoxide, still reinforce.

These insecticides are z. T. rapidly, especially by light, hydrolysis and heat or their combination, advantageously degraded again after being the Anobien beetle or / and their possibly already killed eggs have killed or their effectiveness ha ben. Secondary damage to humans and animals is thus largely or completely avoided the. It is crucial that the nebulizing or fumigating agents only adults and / or eggs, especially Anobien-adults / eggs must kill and not the rest in the material living Stages, especially anobia stages, such as pupae and larvae. Also may be on the The surface of the wooden parts in the unfavorable remaining space deposited eggs, since the smoked and fogging agents can not penetrate deep into the wood, but both the adults as well as the eggs are only on the material surfaces. This is especially true for Anobi around punctate. It has been shown in studies that in particular Ausfüh Partial fumigation during the flying time of the Anobien from the infected Holztei fly out and settle on previously unaffected wooden objects, there hide, wait for a sexual partner or start to lay their eggs there.  

The room fogging or fumigation of the non-guest rest room against Anobien is preferably carried out when the partial fumigation time in the flight time of the anobium beetle falls. Because only within the flight time can outside the partially Beetles occur or if a mating of the females has already taken place, is also one Oviposition possible there.

To minimize the amount of insecticides, especially misting or fumigating agents gene to use, in the other infestation room can also be a volume-reducing hollow body be inflated or introduced.

It is also possible for meherere, also periodic, insecticide application phases, in particular several nebulization and / or Verräucherungsphasen, temporally connected in series to capture as many target pests as possible. In doing so, the insecticide application, in particular the atomisation or fumigation, by means of an automatic dosing machine, Time or insecticide concentration dependent or pest trap dependent, preferably Phe romonfallen-dependent, controlled. For example, one or more Dosierau tomatoes and one or preferably several pest traps in the remaining infested room be present, and as soon as in the or in one of the established traps a target insect, z. B. a Anobienkäfer or moth butterflies, lets catch / give the / the meter / s in Insekti zid, preferably a nebuliser or fumigant, to the air of the rest of the infestation room from. The registration of the target pests in the traps is preferably carried out by means of light barriers. It is also possible in the rest of the infestation room, a specific, deadly for insects pest zidkonzentration maintained, z. By fogging an insecticide, then measuring its concentration in the air and falling below a certain concentration further metering of the insecticide into the room air.

The even distribution of insecticides is best done by fans or other Air circulating devices reached in the remaining infestation room.

The application of insecticides in other infestation room is carried out especially in the cold or in the hot mist process or in the turbo-sprayer process or in the ULV process (= Ultra-low volume), as the insecticide mist or aerosols are particularly long and fine to float in the treatment air. The advantage lies in the long suspension period and in the good penetration, especially in cavities, cracks and crevices, where where especially the beetles and eggs are located.  

Table 1 gives examples of application of some insecticides used.

Further details of the invention will become apparent from the Ausfüh listed below Example and the dependent claims.

embodiment

In a church interior is the high altar of the common rodent beetle, popularly Woodworm called (= Anobium punctatum De Geer) infested. The fumigation of the high altar in July by partial fumigation with a fumigant such. As sulfuryl fluoride, suc gen. For this purpose, a nearly gas-tight Folieneinhausung is created around the high altar and through Introducing fumigant in this Folieneinhausung a fumigation of the high altar by guided. After the construction of the gas-tight foil housing, doors and windows of the Kir closed and then with a nebulizer is a 0.73% Na turpyrethrum extract aerosol misted with 7.6% dichlorvos. The fog is spreading in the do not touch the remaining space of the church and kill old adults of the Anobias (= beetles) and possibly the wooden surfaces of the pulpit, the stalls, the organ, the gallery, the confessionals, etc. deposited eggs within a few minutes to hours, in particular at least after approx. 4-6 hours from. The interior of the church is then ventilated after about 6 to 12 hours and the Natural pyrethrum and dichlorvos are after a few hours by heat, water vapor and light exposure completely degraded or metabolized. After the rest of the remaining Exposure time of the fumigant (total reaction time approx. 72 hours when using Sulfurylfluorid) in the Folieneinhausung at the high altar is, then the Folieneinhausung the High altars removed and by the inventive method thus described are in High altar both the eggs, larvae, pupae and beetles of anobias by the fumigant killed as well as in the rest of the church interior possibly before the film enclosure of the high altar from this out-of-place beetle or from any other vestibule in the rest of the interior of the church Beetle and possibly already deposited eggs killed by the nebulization. Overall The interior of the church is again pest-free, even without the valuable art objects, ceilings, gilding, etc. damage would have occurred.
